Looking at Tim and others comments, shooters as a group walk a fine line. In my view, it is in our interest to keep unsuitable people out but our future also depends on new people taking up the pastime to replace those leaving.
Tim's proposals strike me as being so rigorous they would seriously deter people taking up the sport. It is easy enough to get into shooting if you know someone who can guide you and allow you to shoot before you take the plunge and get licensed. If you're not that lucky, it is a pretty daunting prospect. To spend literally years in probation, during which you could only pursue one type of shooting, e.g. shotgun or rifle, would put so many off. Forcing people to join a club would also be deleterious to our numbers, too many clubs seem to relish formality for its own sake, which hardly gives a welcoming appearance.
If formal training was to be a requirement, and I am not in favour of that, then I would prefer the DSC style course. You pay a modest fee, do a couple of days on a course and you are accredited. Placing people at the mercy of their local club's committee would be a huge mistake.
Questions of how best to assess suitability aside, suitability does seem to be where FLDs should be focussing their attention. As someone (apologies, I can't remember who) has observed, mass shooting by mentally unstable people are a new phenomenon and the Firearms Acts have been geared towards preventing organised criminals, terrorist organisation, insurrectionists etc amassing arms and have a lot of bureaucracy based around this aim. Think of limits on numbers, 1 for 1s, conditions etc which can only be explained (if we discount a wilful desire to make life hard for shooters) as being geared towards stopping people arming a number of people. It is clear what it really needs to focus on is spotting oddballs.
If there is to be real reform, it should focus on clearing FEOs time to assess suitability as fully as possible and strip out all unnecessary rules which do little to nothing for public safety. Personally, I could get behind having further scrutiny placed on my suitability to be granted a license if the process once I had that license was considerably simplified.
